When a request fails to queue it is completed but with its status set to RequestCancelled. Add a check in the requestComplete callback to make sure that the request was completed successfully. For the SimpleCaptureUnbalanced test we need to do this check only if the capture isn't over yet, otherwise the few extra requests that get cancelled at the end, which is the normal behavior, will make the test fail.

2023-12-08meson: Replace hack with usage of '@BASENAME@'Laurent Pinchart
Starting with meson 0.59, the custom_target() function substitutes '@BASENAME@' in the output parameter with the input file name, with the extension removed. This is exactly what we implement manually when generating the IPA interface .cpp files. Furthermore, starting with meson 0.60, the 'name' positional parameter to the custom_target() function is optional, and defaults to the basename of the output file (including the extension). This is exactly the name we compute manually and pass to the function. As libcamera requires meson 0.60 or newer, we can depend on those two features and drop manual computation of the base name. This fixes a warning with recent meson versions that complain that passing a file object to the format() function is a broken feature: WARNING: Broken features used: * 1.3.0: {'str.format: Value other than strings, integers, bools, options, dictionaries and lists thereof.'} Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>

2023-12-07test: gstreamer: Remove videoconvert element from pipelineLaurent Pinchart
The GStreamer single stream test uses the following pipeline: libcamerasrc ! videoconvert ! fakesink The videoconvert element isn't useful as the data is thrown away by the fakesink anyway. We can shorten the pipeline to libcamerasrc ! fakesink to save CPU time and to avoid depending on the gstreamer1.0-plugins-base package to run the unit tests. The test could be further simplified by replacing gst_parse_bin_from_description_full() with gst_element_factory_make(), now that we only add one element to the bin. The extra cost incurred by the bin only impacts initialization time, and using a bin will make it easier to add other elements in the future if needed. Keep the bin, and only drop the videoconvert element.

2023-12-07meson: Tag all installed filesLaurent Pinchart
Meson uses tags to sort installed files in categories, and makes it possible to install a subset of the files using the '--tags' argument to 'meson install'. This is typically used by distributions to split the runtime, development and documentation files into separate packages. By default, meson tries to guess the correct tag for installed files, but can't always do so properly. Mark the install targets that meson can't guess with the correct install_tag. As the feature has been introduced in meson 0.60, bump the minimum meson version. The latest LTS release of all major distributions that libcamera currently targets ship a recent enough meson version.

2023-12-07gstreamer: Implement renegotiationJaslo Ziska
This commit implements renegotiation of the camera configuration and source pad caps. A renegotiation can happen when a downstream element decides to change caps or the pipeline is dynamically changed. To handle a renegotiation the GST_FLOW_NOT_NEGOTIATED return value has to be handled in GstLibcameraSrcState::processRequest(). Otherwise the default would be to print an error and stop streaming. To archive this in a clean way the if statement is altered into a switch statement which now also has a case for GST_FLOW_NOT_NEGOTIATED. In the case of GST_FLOW_NOT_NEGOTIATED every source pad is checked for the reconfiguration flag with gst_pad_needs_reconfigure() which does not clear this flag. If at least one pad requested a reconfiguration the function returns without an error and the renegotiation will happen later in the running task. If no pad requested a reconfiguration then the function will return with an error. In gst_libcamera_src_task_run() the source pads are checked for the reconfigure flag by calling gst_pad_check_reconfigure() and if one pad returns true and the caps are not sufficient anymore then the negotiation is triggered. It is fine to trigger the negotiation after only a single pad returns true for gst_pad_check_reconfigure() because the reconfigure flags are cleared in the gst_libcamera_src_negotiate() function. If any pad requested a reconfiguration the following will happen: 1. The camera is stopped because changing the configuration may not happen while running. 2. The completedRequests queue will be cleared by calling GstLibcameraSrcState::clearRequests() because the completed buffers have the wrong configuration. 3. The new caps are negotiated by calling gst_libcamera_src_negotiate(). When the negotiation fails streaming will stop. 4. The camera is started again.

We make a few small improvements to the code: * The arrayToSet method is prevented from overwriting the end of the array if there are too many values in the input table. If you supply a table, it will force you to put the correct number of elements in it. * The arrayToSet and setStrength member functions are turned into static functions. (There may be a different public setStrength member function in future.) * When no tables at all are given, the configuration is flagged as being disabled, so that we can avoid copying tables full of zeroes around. As a consequence, the pipeline handler too will disable this hardware block rather than run it needlessly. (Note that the tuning tool will put in a completely empty "rpi.cac" block if no CAC tuning images are supplied, benefiting from this behaviour.) * The initialise member function is removed as it does nothing.

2023-11-30libcamera: controls: Use vendor tags for draft controls and propertiesNaushir Patuck
Label draft controls and properties through the "draft" vendor tag and deprecate the existing "draft: true" mechanism. This uses the new vendor tags mechanism to place draft controls in the same libcamera::controls::draft namespace and provide a defined control id range for these controls. This requires moving all draft controls from control_ids.yaml to control_ids_draft.yaml. One breaking change in this commit is that draft control ids also move to the libcamera::controls::draft namespace from the existing libcamera::controls namespace. This is desirable to avoid API breakages when adding new libcamera controls. So, for example, the use of controls::NOISE_REDUCTION_MODE will need to be replaced with controls::draft::NOISE_REDUCTION_MODE.

Add support for vendor-specific controls and properties to libcamera. The controls/properties are defined by a "vendor" tag in the YAML control description file, for example: vendor: rpi controls: - MyExampleControl: type: string description: | Test for libcamera vendor-specific controls.

Similarly, a ControlIdMap control is generated in the libcamera::controls::rpi namespace. A #define LIBCAMERA_HAS_RPI_VENDOR_CONTROLS is also generated to allow applications to conditionally compile code if the specific vendor controls are present. For the python bindings, the control is available with libcamera.controls.rpi.MyExampleControl. The above controls example applies similarly to properties. Existing libcamera controls defined in control_ids.yaml are given the "libcamera" vendor tag. A new --mode flag is added to gen-controls.py to specify the mode of operation, either 'controls' or 'properties' to allow the code generator to correctly set the #define string.

2023-11-25Documentation: Add code of conductLaurent Pinchart
Communities have standards regarding behaviours they consider acceptable or not acceptable, and expect community members to follow those standards. libcamera is no different, even if it has never clearly expressed those standards in a formal code of conduct document. Like software licenses, codes of conduct can be written in a myriad of ways. And like software licenses, using a widely adopted code of conduct instead of writing our own can help bringing clarity. One such standard code of conduct is the Contributor Covenant, stewarded by the Organization for Ethical Source. The Contributor Covenant has been adopted by the freedesktop.org organization, which hosts a large number of projects historically related to graphics, and more recently to multimedia in general. freedesktop.org offers services such as git hosting with CI, which libcamera could benefit from. There is therefore a clear incentive to choose the same code of conduct as freedesktop.org, and no known drawback. As a first step towards this, and to keep the libcamera code of conduct history clear in git, copy the original Contributor Covenant v1.4 from https://github.com/EthicalSource/contributor_covenant/. "v1.4" is ambiguous as the document initially published as v1.4 has received small (but sometimes significant) modifications over time.

2023-11-22ipa: rpi: alsc: Do not allow zero colour ratio statisticsDavid Plowman
The algorithm computes R/G and B/G colour ratio statistics which we should not allow to go to zero because there is clearly no gain you could apply to R or B to equalise them. Instead flag such regions as having "insufficient data" in the normal manner.

2023-11-22gstreamer: Implement element EOS handlingJaslo Ziska
This commit implements EOS handling for events sent to the libcamerasrc element by the send_event method (which can happen when pressing Ctrl-C while running gst-launch-1.0 -e, see below). EOS events from downstream elements returning GST_FLOW_EOS are not considered here. To archive this add a function for the send_event method which handles the GST_EVENT_EOS event. This function will set an atomic to the received event and push this EOS event to all source pads in the running task. Also set the GST_ELEMENT_FLAG_SOURCE flag to identify libcamerasrc as a source element which enables it to receive EOS events sent to the (pipeline) bin containing it. This in turn enables libcamerasrc to receive EOS events, for example, from gst-launch-1.0 with the -e (--eos-on-shutdown) flag applied.
